Cybersecurity is a top-of-mind issue with calls for individual vigilance, national legislation, and international treaties to address gaps that are exploited causing significant harm and financial loss on a daily basis. The vast majority of these calls are well-intentioned though even among the best-intentioned, some are poorly directed. Such is the case with all of the proposals that would introduce security into the International Telecommunication Regulations (ITRs) of the International Telecommunication Union (ITU). more
A few weeks ago, the New York Times published an article saying that the Stuxnet worm, which infected a large number of Iran's nuclear power plants, was a joint effort between the United States and Israel. The program began under former president George W. Bush and continued under President Obama. Last month, the Washington Post ran an article saying that the US and Israel collaborated in a joint effort to develop Flame and that work included Stuxnet. more
I read an interesting article in the Wall Street Journal today entitled Cyber Criminals Sniff out Vulnerable Firms. It's a story of a small business owner in New York whose company was broken into by cyber criminals and stole $1.2 million from its bank accounts, although the owner was able to later recover about $800,000 of that. The moral of the story is that small businesses feel like they are not a major target for online thefts like these. more
As a bit of a history buff I can't avoid a slight tingling of déjà vu every time I read some new story commenting upon the ethics, morality and legality of cyber-warfare/cyber-espionage/cyberwar/cyber-attack/cyber-whatever. All this rhetoric about Stuxnet, Flame, and other nation-state cyber-attack tools, combined with the parade of newly acknowledged cyber-warfare capabilities and units within the armed services of countries around the globe, brings to the fore so many parallels... Call me a cynic if you will, but when the parallels in history are so evident, we'd be crazy to ignore them. more
Declan McCullagh recently opined that the "FBI [and the] DEA warn [that] IPv6 could shield criminals from police." His post was picked-up relatively widely in the past few days, with the headlines adding more hyperbole along the way. So just how real is this threat? Let's take a look. more
According to press reports, DHS is going to require federal computer contractors to scan for holes and start patching them within 72 hours. Is this feasible? It's certainly a useful goal. It's also extremely likely that it will take some important sites or applications off the air on occasion - patches are sometimes buggy (this is just the latest instance I've noticed), or they break a (typically non-guaranteeed or even accidental) feature that some critical software depends on. more
At the end of January, the DMARC (Domain-based Message Authentication, Reporting & Conformance) specification was publicly announced and resulted in widespread media coverage, blog posts and discussion. Since that time various individuals and organizations have been working on writing code for DMARC validators and report parsers. The dmarc-discuss list has been fairly active as various questions and issues have been raised and clarified. Now it is time to see how well the various implementations play together in live testing. more
US presidential candidate Mitt Romney will likely be reconsidering his email passwords after his online email account was reportedly hacked. A hacker claims to have accessed Romney's Hotmail and Dropbox accounts after guessing the answer to the Republican candidate's 'favourite pet' security question. It's suspected Romney used the same password for more than one account. more
The technical press is full of reports about the leak of a hashed password file from LinkedIn. Worse yet, we hear, the hashes weren't salted. The situation is probably both better and worse than it would appear; in any event, it's more complicated. more
An article in Forbes the other day reports on US Secretary of Homeland Security Janet Napolitano's comments that 'cybercrime represents the "greatest threat and actual activity that we have seen aimed at the west and at the United States" in addition to "or other than Al Qaeda and Al Qaeda-related groups."' ..."Napolitano cited a study commissioned by Symantec that put the total worldwide cost of cybercrime at $388 billion -- higher than the global market for heroin, cocaine and marijuana combined." more
